5.03 Formation of Four-Membered Heterocycles

Autor: J. Marchand-Brynaert, R. Robiette

This review focuses on new developments in [2+2] cycloadditions leading to four-membered heterocycles (β-lactams, β-lactones, β-sultams, azetidines, etc.) which appeared between 1992 and 2011. A special attention is drawn to the mechanistic aspect

A β-aminoacid ester was successfully derivatized to yield to 4H-1,2-4-triazol-4-yl-propionate (βAlatrz) which served as a neutral bidentate ligand in the 1D coordination polymer [Fe(βAlatrz)(3)](CF(3)SO(3))(2)·0.5H(2)O (1·0.5H(2)O). The temperat

Discovery and validation of a new family of antioxidants: the aminopyrazine derivatives

Autor: M L N, Dubuissona, J-F, Reesa, J, Marchand-Brynaert

Publikováno v: Mini reviews in medicinal chemistry. 4(4)

Coelenteramine (2-amino-1,4-pyrazine derivative), one of the metabolites of the oxidative degradation of coelenterazine (imidazolopyrazinone derivative), is endowed with excellent antioxidative properties towards ROS/RNS, like its mother-compound. Th

Covalent grafting of fibronectin and asialofetuin at surface of poly(ethylene terephthalate) track-etched membranes improves adhesion but not differentiation of rat hepatocytes

Autor: S, Jaumotte-Thelen, I, Dozet-Dupont, J, Marchand-Brynaert, Y J, Schneider

Publikováno v: Journal of biomedical materials research. 32(4)

The adhesion and differentiation of rat hepatocytes onto track-etched poly(ethylene terephthalate) (PET) membranes were studied. Native or [3H]methylated fibronectin (FN) or asialofetuin (ASF) were immobilized onto oxidized PET membranes, preactivate

Design, synthesis and evaluation of D,D-peptidase and beta-lactamase inhibitors: azapeptides, oxapeptides and related heterocycles

Autor: J, Marchand-Brynaert, P, Mougenot, Y, Combret, D, Belotti, N, Guillot, L, Ghosez

Publikováno v: Farmaco (Societa chimica italiana : 1989). 50(6)

Reactive molecules susceptible to form stable acyl enzyme intermediates with D,D-peptidases and beta-lactamases were designed as potential irreversible inhibitors of Penicillin Sensitive Enzymes (PSEs). The structures examined were a series of azapep
